' invention relates toforms for concrete 7 7 structures and moreparticularly to a form lor wall tie for trans'versely connecting thewalls ofaconclrete Itis customary in thevconstruction of'concrete'form's toprovide side walls of boards attached to uprights'oi'studding; 'Theupoppositely, disposed and are interconnected suchcasethe'transverse ties do not-per sedethe form-walls; I It is usualsuch'constru'ction to employ Wooden spacers which are interposed atintervals between the form walls and whichxmust be removed as theconcrete is formed. 9 I f t p The present form of tie is pre-iormedinpredetermined sizes inv accordance with the thickness'o'f the concretewall or the spacing of theform walls. The tie is'adapted to de- I maybefc onnected with the tie in various termine the spacing of the'wallsof the forms and to prevent spreading. The use of the present tie alsoenableslthe eliminationfof" a portion ofthe upright struts or stu'ddingor "3U thespacin'g of suchstruts' at greater intervals. In its preferredform the presenttie comprises a "single strand of wire having at, one"end short cross arm attachedthereto and at itsopposite end inpredetermined spaced such short cross arms spaced one from the other adistance substantlally equal to the thiekn ess of the boards formingtheside-wall' of the form, In applying the ties the end hav ing thesingle cross 'arm isjpassed between successive form b oards adjaeent toan up right strut or studiding-withthe shortcross arm atthe innersid'eort the form wall.

Consequently the struts orstudding may be The suc- I cessive ties are arranged in reverserelation, that is to say, Whereas the end of the tie having the singlecross armis passed about the offset infrelation with each other strut orstudding at oneside of the form and the double cross arms in theopposite end of tudinally of the form, will be arr anged with its singlecross arm engaging the last men tioned wall of the form and extendedabout a strut on the side ofthe form with which the double cross arm wasengaged and theend of the. tie straddle the form board of the oppositewall inthe next succeeding'tie, longithe secondtie,'carryingthe spaceddouble cross arms will be engaged with the'opposite form wallCorresponding tothat contig uous to the strut or studding with which'thesingle cross arm end of the engaged.

and unlikely to get out of shape or alignment.

A further object of the invention is to providefan improved form of tiewhich may be easily and quickly applied and which will predetermine thespacing of the form walls. A further object of the invention is toprovide a form tie'whieh will tend to hold the form boards in theiradjustedposition thus reduce to a'minimum the use 0 studding.

At the opposite manner as the cross arm lof the described construction-L Instead of interconnecting su'ch nehor;members :9 and '12 by an intermediatestrand 8, such anchor members may'fiap*strip of material 15: shownin Fig. 6. In such case the strip 15 istwisted at;16 to enable it to pass about the supporting struts I orstu'ddingQ. Theffingers 13 ando l lyat'one endofthe stripengage'theinner side ofthe form wall while the spaced lingers 1'0 and-11at the opposite end of the strip 15 straddle succeeding boards of theopposite wall of the form.- a I In lieu of the spaced cross armsorfingers heieto'foredescribed, thetie or spacerstrands maybeprovided withspaced knots 17 as ill lustratcd in Fig. 7. In this instance the tie sstrand 3 is shown 'as: provided with a single knot at one end,corresponding to the cross jarm l andserving alike purpose, While at Iect matter hereof is engageablewithone wall and about the studding orsupport and is engageable with the opposite wall independent 01 astudding or upright, there are conditions inetj'in buildingconstructionwherein it may be desirable to employ oppos tely disposed uprightsorstuddings. In such" case, a tie a strand 3 having a single cross arm 4at each end as illustrated in'Fig. 8 may be employed; In such case, abight is formed at each end of the tie strand Sto embrace the oppositelydisposed studding oruprights W In other words, in lieu oI' -the doubleanchor fingers 5 and 6, which are intendedforengagement with'the formboards intermediate succeeding studding orl-uprights, the single-crossarm 4 twithits studding engaging bight is dupliicated at the oppositeend of the tie.

' For thoseconditions where itis desired to ding, or atpoints Whoreuprights or studding,

brace a form intermediate uprights or studare not available, it is quitepractical to duplicats the spacedanchor fnigers or'cross arms and 6 ateach end ofthe tie strand as shown i 9. By providing such cross arms oranchor lingers 5 and6 in spaced pairs at each cndof thestrand 3, suchstrandmay be uti-' li'zed tobrace and tie together the sidewalls of theconcrete form wholly lndependent of supporting struts-orstudding. Theconnecting strands 3 and 15 being comparatively .thin areeasilyjembeddedin themargms of the form boards by the Weight of thesucceeding boards above or by a hammer blow. Thus theexisten'ce ofintervening zcrevices or cracks sufiiciently large to permit leakage ofthe concrete is entirely avoided. The use of thepresent form of tieinsures the proper and accurate spacing 'ofithe form Walls and anchorsthem one to another to preventbulging or collapseiunder the pressure ofthe concrete there within. Moreover, by use ofthe present form o-iftieand spacer member the use ofnails is almost entirely obviated. The

top course'of boards is preferably nailed to prevent the "boards fromfloating up or ris lug-as concrete is poured nto the form. iVhrle, 1tdes1red,'the boards may be nailed to the studding or uprights in theusual manner, it has been found in practice'that the present tie issufiicient under all ordinary circumstances and conditions to securetheform boards in place. Notonly does the. use of these ties contribute tothe strength of the form and facilitatethe rapidity with which a formmay be constructed, but they also very materially facilitate the removalof the forn'ia'fter the concrete hassct; This isdone by cutting thebight of the Wire strand passing about the studding or uprightson oneside oi thewall and by cutting or. knockingjofl' the anchor fingers 6 atthe opposite side of the wall leaving the intermediate tie strand 3embedded in the body of concrete.

While the present tie is primarilyintended for use in securing andbracing concrete forms itwill also be found useful in securing crating,bracing and reinforcing large shipping boxes, for racking materials orfor bracingparts of buildings Obviously, thetie member may be made inany lengthand of increased strength to accommodate it to variousconditions of use. I a From the above description it will be apparentthat there is thus provided a construction of the character describedpossessing the particular features of advantage before enumerated asdesirable bntwhich obviously is susceptible of modification, in itsform, proportions, and arrangement of parts, without departing from theprinciple involved or sacrificing any of its advantages.

While in order to comply with the statute the invention is described inlanguagewmoro or less specific as to structural features, it is tobeunderstood that the invention is not limited to the specific detailsshown, but that the meansand construction herein disclosed comprise thepreferred form oiiseveral mod es ofputting the invention into eil'ect,and the invention is therefore claimed inany of its forms ormodifications within the legitimate and valid scope of the, appendedclaims.
